Hello everyone I'm new to CancerCompass. I am a 15 year old female, and I am concerned about tailbone pain I have been having for the past 3 months or so. It mainly hurts when I move while I'm sitting down or in bed once in a while. My father, who passed away, had colon cancer and I do know one of his symptoms was tail bone pain. He also had constipation and blood in his stool. I have not had any constipation or blood in my stool, I am just concerned about this tail bone pain I have been having. Could it be cancer related?..
